If you have the oil pan off, the front cover can be removed much easier than with the pan on. The front cover is sandwiched between the head and the oil pan. And I've never had a problem with any silicone gasket makers. Did you allow it to set properly before running the motor, and also, did you make the beads correctly?
As far as the valve cover threads, maybe try a heli-coil thread repair kit. They are easily found at auto repair shops, though metric sizes are bit more difficult to find.
